Hi Butters,It's not known. There has been some evidence that they're going by DS submission date still and some are going by the case number. The strong speculation is that there are two groups processing DS260s in both ways. However, note that we've seen 2 digit, 3 digit case numbers and also cases like 3k submitted in late June/July/... being processed. How do they manage the different regions and similar questions, noone knows or will ever know for sure. It's quite chaotic and they seem to be just taking the process much more seriously.
Another thing is that they were sending ready for scheduling emails days ago, but they haven't done it. Either they don't send emails when they process the forms or they're focused on scheduling and haven't processed or both. Or even maybe one group sends emails when they process DS260s but the other doesn't. Keep in mind the whole system updates going on.
Regardless, they were done with May submissions which accounted for about 40% of all submissions before the start of fiscal year. They used half of September, October, November and half of December (three months). This means it would've taken them by March to finish all the DS260s submitted before start of Fiscal year by the workforce at the time. So, given the increased workforce (Docs processing group re-positioned) , it would take them about that or less regardless of how they process DS260s. For example I submitted mid-September (reason for my obvious bias in the optimism) and the CN group processing will be processing cases in June/July/August/September (Majority submitted by here)/ . And the submission date group will go forward from June, so regardless there's always one less DS260 to get to mine.
Another thing I would speculate but can't be sure is that: They have the normal group processing DS260 by submission date. DQ people processing by case number. And some of these along with other group scheduling interviews. Given that they are trying to fill as many interview slots as possible, it's plausible that they also go by embassy capacity and if a current person has embassy capacity, process the person's DS260 quickly ahead of both queues and schedule him/her.
Anyways, I think by March they could be done processing the majority of DS260s and the details of this procedure won't matter to us as it did a month ago. Then, the important thing will be the scheduling of interviews and the effect of Covid variants on the capacities and etc.
Are you on the DV2022 tracker?
It'd be nice to add your case there so we have more data for analysis.
